Abstract
This study aimed to evaluate the clinical efficacy, safety, and feasibility of performing endoscopic submucosal resection with a ligation device (ESMR-L) after apical mucosal incision (AMI) for the treatment of gastric subepithelial tumors originating from the muscularis propria (SET-MPs). 14 patients with gastric SET-MPs were treated by ESMR-L with AMI between December 2016 and May 2017. The complete resection rate, operation duration, and postoperative complications were collected. All patients were followed for 2 - 6 months. The complete resection rate was 100 %, the mean tumor size was 10.71 ± 3.45 mm (7 - 18 mm), and the median operative time was 18.5 minutes. Perforation occurred in four patients, with all lesions being completely repaired endoscopically. No delayed bleeding or peritoneal signs were observed. No residual lesions or recurrence were found during the follow-up period. AMI with ESMR-L appears to be an efficient and simple method for the histological diagnosis of gastric SET-MPs, but it carries a high perforation rate and cannot guarantee cure.
